Filed: 1972-03-16
Abstract: 1356353 Earthing rods ALLEGHENY LUDLUM INDUSTRIES Inc 16 March 1972 [16 March 1971] 12343/72 Heading H2C [Also in Division F2] An earthing rod comprises a thin-walled tubular shield 2 of corrosion-resistant material, e.g. stainless steel surrounding a thin-walled tubular conductor 4 of low impedance metal, e.g. aluminium or carbon steel and a core 6 of semirigid, e.g. plastics material substantially filling the tubular conductor. In another embodiment, Fig. 2 (not shown) a further tube (5) of steel may be provided in addition to or instead of the core 6. A driving point 8 may be provided to enable the rod to be driven into the ground and to preclude direct contact between the tubular conductor and the ground. It is stated that the shield and driving point prevent the tube from galvanic corrosion, the tubular conductor enables the rod to handle large current surges and the further tube and/or core permit some flexing of the rod during installation while preventing buckling. The tubes, which need not be circular in cross-section are typically 8 feet long, 5/8 inches O.D. and may have wall thicknesses much less than 0À07 inches i.e. 0À03 inches. The core is preferably under compression in the tube and may be of an epoxy, polyurethane or an elastomeric material i.e. non-reactive with the material of the rest of the rod. The rod may be made by drawing the tubes over the core; if the core has the same diameter as the inside of the tubular conductor then the required compression is achieved. Alternatively, oversize tubes may be used and subsequently drawn down, the tubes may be extruded over the core, or tubes may be filled with a core material that expands on hardening. A coupling device 12 (see Division F2) is also described.

Patent GB-831889-A (GB)
Title: Process for the oxidation of anthracene to anthraquinone
Filed: 1957-04-18
Abstract: <PICT:0831889/IV (b)/1> Anthraquinone is prepared by catalytic oxidation of anthracene wherein anthracene is atomized to form a liquid mist, the liquid mist is then rapidly vaporized and the resulting anthracene vapour is mixed with a stream of a hot oxygen-containing gas, and wherein the supply of liquid anthracene to be atomized and the supply of hot gas are so adjusted relatively to one another that the proportion of anthracene in the gaseous mixture so formed does not exceed the critical lower explosion limit.  The actual oxidation takes place in a known manner preferably using air and an alkaline vanadium oxide catalyst.  In a preferred embodiment (Fig. 4), anthracene is melted in vessel 21 and supplied by pump 22 to atomizer 23.  Steam is generated in boiler 24 and passes through superheater 25 to the atomizer.  Atomization and vaporization take place in zone 26 and the vapour stream passes through one of the filters 29 depending on which of the valves 32 is open.  The filter may be porcelain, glass wool, ceramic or sintered metal and whichever one is not in use may be cleaned. The anthracene vapour and steam is then mixed with hot air from blower 27 and heater 28, the composition of the mixture being regulated by pump 22 and blower 27.  The exit stream from catalyst zone 30 passes to separator 31 which is insulated or even heated to prevent the water vapour condensing, and the mixture then passes to a filter 35 where the bag 36 retains the solid anthraquinone which is recovered through 37 while the steam and air pass out through 38.  Mixing the anthracene vapour and air outside the atomization and vaporization zone enables the composition of the feed to the catalyst zone to be controlled accurately. Specification 786,374 is referred to.
